“COLLIDING RIVERS SIGN” IN URINARY BLADDER IN 18FDG PET/CT SCAN
Abstract
A 75 years old lady known case of recurrent diffuse large B-cell lymphoma (DLBCL) referred for 18-fluoro-deoxyglucose (18FDG) positron emission tomography and computed tomography (PET/CT) without contrast enhancement. Images showed widespread hypermetabolic deposits with soft tissue components at multiple skeletal sites consistent with recurrent DLBCL. Interestingly urinary bladder showed a unique presentation of hot and cold segments resembling Colliding Rivers.
